The Presence of Virulent and Multidrug-Resistant Clones of Carbapenem-Resistant Klebsiella pneumoniae in Southeastern Brazil.
Article in Current microbiology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The emergence of carbapenem-resistant Klebsiella pneumoniae (CRKP) represents an urgent threat to global public health due to the limited therapeutic options available to control this pathogen. This study aims to analyze the molecular epidemiology, antimicrobial resistance and virulence profile of CRKP isolated from patients at hospitals in Southeastern Brazil. KPC and other beta-lactamase genes were detected in all strains, which were also multidrug-resistant (MDR). In addition, 11 strains showed resistance to last-resort antimicrobials, such as colistin and tigecycline. MLST analysis revealed eight different sequence types (ST11, ST37, ST147, ST340, ST384, ST394, ST437, and ST628), being two (ST628 and ST394) reported for the first time in Brazil. Strains belonging to the clonal complex 258 (CC258) "high-risk clones" were prevalent in this study. The Galleria mellonella model showed the emergence of virulent CRKP strains in the healthcare environment and, suggests that colistin-resistant strains were associated with higher virulence. This study shows the presence of virulent CRKP-MDR strains in hospitals across Southeastern Brazil, and draws attention to the presence of highly virulent emerging CRKP-MDR ST628 strains, showing that virulent and resistant clones can emerge quickly, requiring constant monitoring.
